Hi,
I am working on a vb.net windows application. (windows 2000 / .net 1.1)

The application dynamically creates a picturebox and loads a picture into it from disk. Then after a couple of seconds the app needs to delete it.
However, when I try to delete the file I get this error:

An unhandled exception of type 'System.IO.IOException' occurred in microsoft.visualbasic.dll
Additional information: The process cannot access the file "C:\test.Png" because it is being used by another process.

But the only process that could be using it is the app itself.
I've also tried this to no avail:
    pic1.Image=Nothing
    Controls.Remove(pic1)
    Kill("C:\test.Png")

Any ideas...?

The problem is the Image.FromFile locks the image, and you need to release resources.  You need to call the Dispose method to release resources.

Thanks that seems to have corrected the problem!

This may be related to a similar issue I have with the webbrowser control (AxSHDocVw.AXWebBrowser).
